Can I reuse the rear axle abs reluctor ring and retaining sleave for my 1996 sidekick X90?

I don't think you'll be able to transfer the old parts to the new parts. You may have parts for a different vehicle application. It's best to get with the source of the parts to find out why there is a variance.

I have no knowledge of the exact set up is on this vehicle - however “retains sleeve” indicates a press on fit - if that is the case then the retainer can not be reused.. Recommend purchasing the correct parts - look for bearing application that stated with abs.
